    Construction and Expansion of Dictionary of Idiomatic Emotional Expressions and Idiomatic Emotional Expression Corpus

    Objective: In the study of sentiment estimation from language, methods focusing on words, phrases, sentence patterns, and sentence-final expressions have been proposed. However, it is difficult to deal with a wide variety of emotional expressions by only assigning emotions to words and phrases. In particular, it is difficult to analyze metaphorical expressions and idiomatic expressions on a word-by-word basis, and it is impossible to register all expressions in a dictionary because new expressions can be created by flexibly replacing words. However, it is difficult to determine the constraints on the words to be replaced, and not all expressions can be registered in the dictionary as sentence patterns. Methods: In this paper, we construct a dictionary of idiomatic sentiment expressions, which contains idioms expressing emotions. In this paper, we construct a pseudo-emotional corpus by collecting utterances containing emotional idioms from social media and automatically assigning emotions expressed by the idioms. Results: This corpus includes expressions other than idioms, and can be an effective resource for estimating emotions in sentences that do not contain idioms. In this study, we create an emotion estimation model for utterances based on the constructed corpus, and conduct evaluation experiments to explore the problems of the idiomatic emotion corpus. In addition, using the constructed sentiment corpus, we investigate how to expand the dictionary of sentiment expressions in idiomatic phrases by using deep learning methods. Conclusion: Using the corpus of idiomatic sentiments constructed by the proposed method as training data, models with and without idioms were constructed by machine learning models. The results show that the F-values of all emotions with idioms exceed 0.8. On the other hand, when idioms were not included, the F-values tended to decrease overall. However, the F-values of emotions such as "shame" and "excitement" were around 0.7, indicating that the characteristics of emotional expressions other than idioms were expressed

    Lithium was contained rich in ocean sardine and anchovy; especially concentrated in the back-bone, head or gill of the fish, which were related with calcium as matrix components. In leaching experiments lithium was softly dissolved from the fish bone by shaking with a 0.1mol/l hydrochloric acid or a 0.1mol/l acetic acid solution after washing and removing the surface sea-water on the fish with water. The lithium leached in the acid solutions and remained to the residue was determined by flame photometry using the atomic absorption spectrophotometer with air-acetylene flame, after the decomposition with nitric-perchloric acid mixture. In the gill, head and back-bone of anchovy, 73, 71 and 71% of total lithium were dissolved with 0.1mol/l hydrochloric acid, respectively. Same leaching results were obtained for calcium; 78〜84% of total calcium were also dissolved with the same leaching solution. The ratio of lithium and calcium dissolved in hydrochloric acid or acetic acid were almost constant to be 3〜8×10^ regardless of the sort of acid, the number of leaching fraction and the part of fish bone, and the ratio in the hydrochloric acid leaching was constant to be 7±2×10^. Those values was nearly equal to the ratio of 6±2×10^ (n=9) of total lithium content of anchovy. It was, therefore, supposed that lithium was existed in fish bone as calcium compounds which was likely apatite or calcite, or a part of total lithium presented as the complexing component with calcium, which was passed through the dialysis filter less than 10000 as molecular weight

    Classification of Smartphone Application Reviews Using Small Corpus Based on Bidirectional LSTM Transformer

    Get PDF
    This paper provides the classification of the review texts on a smartphone application posted on social media. We propose a high performance binary classification method (positive/negative) of review texts, which uses the bidirectional long short-term memory (biLSTM) self-attentional Transformer and is based on the distributed representations created by unsupervised learning of a manually labelled small review corpus, dictionary, and an unlabeled large review corpus. The proposed method obtained higher accuracy as compared to the existing methods, such as StarSpace or the Bidirectional Encoder Representations from Transformer (BERT)

    Relationship Between Personality Patterns and Harmfulness : Analysis and Prediction Based on Sentence Embedding

    Get PDF
    This paper hypothesizes that harmful utterances need to be judged in the context of whole sentences, and the authors extract features of harmful expressions using a general-purpose language model. Based on the extracted features, the authors propose a method to predict the presence or absence of harmful categories. In addition, the authors believe that it is possible to analyze users who incite others by combining this method with research on analyzing the personality of the speaker from statements on social networking sites. The results confirmed that the proposed method can judge the possibility of harmful comments with higher accuracy than simple dictionary-based models or models using a distributed representation of words. The relationship between personality patterns and harmful expressions was also confirmed by an analysis based on a harmful judgment model

    The purpose of this research is examining the impact of equivalence assessment of auditing by European Union on Japanese auditing system. In this assessment International Standards on Auditing and US Generally Accepted Auditing Standards are allowed to be equivalent auditing standards. Japanese auditing standards are not same with ISA, but sre almost equal with ISA. Japanese auditing standards might noy be assessed as equivalent auditing standards

    Spectral Decomposition of Path Space in Solvable Lattice Model

    Full text link
    We give the {\it spectral decomposition} of the path space of the U_q(\hatsl) vertex model with respect to the local energy functions. The result suggests the hidden Yangian module structure on the \hatsl level ll integrable modules, which is consistent with the earlier work [1] in the level one case. Also we prove the fermionic character formula of the \hatsl level ll integrable representations in consequence.Comment: 27 pages, Plain Tex, epsf.tex, 7 figures; minor revision. identical with the version to be published in Commun.Math.Phy
